Subject: building ruby for speed: wise or otherwise?

My active record based script is taking longer than I'd like.
While I wait for approval to get a faster machine :-) I'm wondering
about rebuilding ruby 1.8.2 (which I have now) and changing the
CFLAGS from the default 
CFLAGS=-g -O2
to 
CFLAGS=-O3
or something of the sort.  I'm presently using gcc-3.4.3 on
Solaris9.  Has anyone done this and if so is there anything I should
watch out for?  ISTR reported problems when building other packages
with high -O values in the past. 

Would the answer be different for gcc-4.0.2?

        Thank you,
        Hugh
